v ny -em Application filed February 4,1913. Serial No. 746,234.

To alley/ mm it may macaw:

is it known that 1, Que l3. Yaw citizen of the United States and.resident of Arlington, in the county of Hudson and State of New Jersey,have invented certain new and useful improvements in Typell iitinghilachines, of which the following is a specification.

My invention relates to typewriting machines and is directed moreparticularly to the paper controlling, guiding or feeding means in suchmachines.

it has been common heretofore to employ loose-leaf work sheets providedwith keyhole slots such, for example, as those shown in 5 oi theaccompanying drawings. 'lhese key-hole slots enable the sheets to beboundin a loose-leal cinder after the sheets have been filled in on themachine Such sheets are employed in condensed record billing. and-othercharacters of worln and dificiilty has been. encountered heretofore infeeding such sheets through the machine by' reason Of the liability ofthe edges of the work sh ets, where the key-hole slots are provided,catching against certain oi? the paper feeding or guiding devices andpaper apron, etc. hicieover, din iculty has been found heretofore byreason of the lia- .bility of the lower-or bottom edge of the work sheetcatching on the front edge of the paper apron when the sheet has beenfed forwardly a sufficient distance to carry the bottom edge of the worksheet above the front edge of the paper apron, and when an attempt isthen made to hack up the sheet.

'lhe main object oi my pTe'sent invention is to overcome these and otherdiliiculties,

' and to provide simple and ellieient means for effectively guiding awork sheet as is being fed either backwai'dly or forwardly throughthesnachine, H

To the above and. other ends which will hereinafter appear, my inventionconsists of the features of .COnsti'uction, arrangements of parts andcombinations oi devices set forth in the i llowingj description andparticularly pointed out in the appended claims.

In 1e accempaiwingdrawings wherein like reference chars? "designate someparts in time all; went vi we 4 1 and 2.

the carriage on a ure 1 is a transverse sectional view of a portion of acarriage of a typewriting machine embodying my invention Fig. 2 is adetail rear elevation OTE one ,ffillll of paper finger carrying a marginfeed roller and constructed in accordance with my present invention.Fig. 8 is a like View of another form of the construction. Fig. 4% is afrag inentary longitudinal sectional'view of device shown in Fig. 3.Fig. 5 is a fragmentary "front elevation of a carriage equipped. with apaper finger such as is shown in Figs.

l have shown my invention in the present instance embodied in a frontsti'ike machine, the carriage shown being that of a No. 10 or l lo. 11Remington machine, lit should he understood, however, that the inventionmay be embodied in various styles of typewriting machines. The carriagecomprises end. plates 1 united by ross bars 2, 3 and A cylindricalrctative platen 5 mounted v platen shaft 6 in the usual manner. Frontand real paper feed sellers '2 and 5% respectively cooperate with theplaten in the usual manner, such rollers extending through openings in apaper apron 9 which terminates at its iorward end at the line indicatedby the reference numeral 10.

Forwardly extending arms ll formed on the end plates are apertured toprovide bearing openings for the outer cylindrical ends of rock shafts12. The inner cylindih cal ends of these rock shafts are supportedinbearings 13 on a bracket 14 secured by screws '15 to the cross bar 2 ofthe carriage. Each of the rock shafts 12 is angnlai'in ciz'oss sectiohexcept at its reduced ends which aie received in the bearings inthe endplates and. in the bearings of the bracket 14. A paper feeding, guidingor controlling device or paper finger, designated as a whole by thereference numeral 16,,is mounted on each Tool: shaft 12 to turntherewith into and out l atentedelne'. iaieis;

of operativeposition and for adjustment;

sexing; l9, which spring tends to tion.

. a the movement of the bell crank lever and the parts connectedtherewith in one direc- The other arm 22 of the bell crank lever isprovided with a finger piece 23 by which the bell crank may be turnedagainst the power of the spring 19 to move thepaper feeding orcontrolling device 16 carried by the associate rock shaft away from theplaten and out of coiiperation with a work sheet'24 carried thereby. Thepaper guiding, controlling or feeding device 16 in the present instancecomprises a sheetmetal arm formed at one end with a hearing orsupporting portion 26 having a rectangular opening 27 therein to receivethe associated 2 rock shaft 12. The paper controlling device is thusconnected to turn with th-e rock shaft but may be shifted longitudinallythereof to efi ect an adjustment of the paper feeding devicelongitudinally of "he platen. The

25 upper end of the paper feeding device is bifurcated to form arms 28between which is received a margin feed roller 29 mounted to turn on apivot 30 fixed in bearings 31 on the arms 28. A forwardly projectingfinger 30 piece 32 extends from the bearing portion 26 of each paperfinger or controlling device 16 in order to fa :ilitalc an adjustment ofthe paper linger longitudinally of the platen. The parts thus fardescribed constitute a 5 port-ion of the usual equipment of a No. 10

or No. ll-Remington machine and fiirther description thereof is deemedunnecessary.

From an inspection of Figs. 1 and 5 it will be seen that the rock shafts12, by which 0 "the paper fingers are supported, are situated below theprinting line indicated at a and thatthe fingers extend upwardlytherefrom in front of the platen and across the print ing line, It willalso be seen that the usual keyhole slots 33 in the work sheets arearranged at the left-hand edge thereof and pass beneath the body portionof the paper finger in the backward and foi ward feed of the work sheet.In order to prevent the 1 5b edges of the work sheet at the key-holeslots therein from engaging the supporting portion 26 of the paperfinger and from catching in the space indicated at 34 (Fig. 1) betweenthe lower end of the paper finger and the body portion thereof, I haveprovided a deflecting plate or guiding shield 85, This plate or shieldextends in the general direction of the length of the paper finger andis secured thereto at one end by any suitable means. In the constructionshown in Fi s.

1, 2 and 5, thisshield 35 is riveted to t e paper finger at its upperend, as indicated at 86, and is preferably hard soldered to the paperfinger at this end. 1 preferably reduce the thickness of the metal ofthe deot ones at the lower end 38 thereof, where it has a slightdownward and. forward curve just before it reaches the forwarn edge 10of the paper apron. It will be observed that the def] ecting member isflexed and extends away from the body portion of the paper finger as thedeflecting member ends downwardlyso as to cover the opening 34 in thesupportingportion 26 of the paper finger, such supporting portion beingreceived in part- 'substantially between the two arms which constitutethe paper guide, one of he arms being formed by the main body pen tionof the paper finger and the other by the deflecting plate or shield 35.

It will be understood that in the forward movement of the work sheet itwill be maintained snug against the platen at all times until it leavesthe margin feed roller so that there is no opportunity for an edge ofthe work sheet to engage or he a-nght on any of the paper feedingdevices. That portion of the work sheet which CO1 'ns key-hole slot 33as it leaves the parrot apron in the forward feed of the work sheet isi1nmediately received beneath the deflecting member 35 and maintainedsnugly pressed against the face of the platen by the deflect ing member35. if any attempt is made to back up the sheet the deflecting membermaintains the edges of the keyhole slot snug against the platen untilthey pass the forward edge of the paper apron by which they are pressedagainst the platen. If the work sheet be fed forwardly to a positionwhere the lower or'bottom edge 39 thereof passes beyond the forward edgeof the paper apron and the paper should. be backed up from such positionthere is no liability of the bottom edge of the work sheet engaging theforward edge of the paper apron as the deflecting member ,35 willaccurately direct the edge of the work sheet into the slight spaceformed between the forward edge of the paper apron and the body portionof the platen. It will be understood, therefore, that l have providedsimple and etlicient means for accurately guiding ad centrolling thework sheet in such a manner that the edges thereof at the keyhole slotsor at other portions of the. work are prevented from engaging orcatching on any of the paper feeding or guiding devices or the means bywhich they sup in place.

In Fig, 3 and l-Z have modifica- 1 god ess;

' shield 35 is formed integral with the body portion 25 of the paperfinger and is in the nature of a spring tongue which projects rearwardlyfrom the body portion oi the paper finger from the polnt of attachment10 where it joins the paper linger proper. The lower end of thedefiecting'member 35 is curved slightly at 38 substantia'liy in thepreviously described construction. Otherwise the parts are the same asthose previously described. It should be understood that any suitablemeans may be pro vided for connecting a spring deflecting member,nrshield 35 or 35* to the paper finger to operate substantially in themanner set forth.

While I have shown the paper controlling device 16 at the left-hand endof the platen it will, of course, be understood that a similar devicemay, if desired, be provided at the right-hand end of the platen forcontrolling the work sheet at the righthand as Well as at the left-handside edge portions thereof.

Fro-mthe foregoing description it Will be seen that in each, of theconstrnctionsshovvn the paper finger has a deflecting member whichextends from the body portion of the paper finger to a point "Where itis substan tiaily flush with one edge of the supportihg member 26; thatin each. of said constructions the paper finger is turned at one end toform a bearing and has a deflecting plate projecting from the bodyportion of the paper finger and extending over the turned end of thelinger; that in each case the paper finger may he said to comprise twoparts which are spaced apart at one portion of the paper finger andconverge at anoth' r portion thereof to form in effect a C(E'HtliTtiousconnecting surface made tip inpa'rt oi one member and in part of theother meinher, said members being united at...tlie pfiint ofconvergence; that in each instance "the deflecting shield has itscontact surface in register with the contact surface of the paper fingerand forms in effect a continuation thereof; that the shield. is tried atits upper end to the paper feeding device or finger and is deflected.therefrom at the lower end of the shield; and that in "each instance thebar or supporting member 12 ex tends to the rear of a line coincidentwith or forming a downward continuation of the contact'face 87 of thepaper feed device and in the rear of a plane tangent to the front faceof the platen, Where the'har-andthe rear portion of the part 26, wouldofier an.

obstraction against rwhich an edge of a sheet might catch in thelaichward feed of the sheet were it not for the deflecting member '35 or3-5 What I claim as'new and desire tosecnre by Letters Patent, is
